Description
Technical field
The present invention relates to a kind of smoke processing system of rotary kiln, relate in particular to a kind of novel environment friendly rotary energy saving kiln gas treatment system.
Background technology
Kiln is mainly the pollution of flue gas to atmosphere to the pollution of environment.The kiln that directly burns coal is the most serious to the pollution of atmosphere; Burning heavy (slag) oil takes second place; Burning outization coal gas and contaminated by diesel oil are minimum, as long as burning is normal, generally can reach the requirement of country to Industrial Stoves dust emission standard.Coal-fired furnace to the pollution of atmosphere mainly comprise in cigarette, dirt and waste gas pernicious gas as
,
,
deng pollution.
Rotary kiln is the new model kiln just occurring in recent years.The difference of rotary kiln and early stage tunnel cave is: the kiln of tunnel cave is motionless, and adobe is moved; The adobe of rotary kiln is motionless, and kiln (being kiln car) is mobile.Rotary kiln utilization annular fortune base system is transported to each position, firing chamber by green compact; Green compact code is good motionless, and kiln car walking is included green compact in by criticizing; Green compact are dried in kiln car, humidity discharging, preheating, roasting, insulation, cooling; Burned city brick from kiln car afterbody out; The direct Kai Ru of automobile firing chamber's entrucking.
In rotary kiln production process, the flue gas producing after coal combustion (waste gas), sends into preheating zone (drying room) through flue and blower fan, and waste heat makes full use of.But the feature because rotary kiln moves, is difficult to the discarded fume treatment auxiliaries such as desulfurizing tower of sending in preheating zone, generally adopt nature discharge.The mode meeting severe contamination ambient air that this flue gas discharges naturally, causes environmental pollution, is unfavorable for environmental protection.
